Lecturer in Mathematics/ Admissions officer

Biography I was an undergraduate at the University of Manchester, where I studied mathematics from 1975-1978. I then undertook a PhD in fluid mechanics, under the guidance of Mr. Eric J. Watson, in the department of Mathematics at the University of Manchester from 1978-1981. This was followed by two post-doctoral awards at Imperial College, University of London, under the guidance of Prof. Frank T. Smith, from 1981-1984. Subsequently I was appointed to a "new blood lectureship" in the department of applied mathematics at the University of Hull in August 1984.

Subsequently, most of my life has been centred about the University of Hull. I took a year of absence in 1988-89, where I took on a visiting lecturer at Iowa State University, and worked with Alric Rothmayer. At the same time I was also a visiting researcher at NASA Lewis at Cleveland, Ohio. This led to a research visit at NASA Langley, in Virginia in 1990.

I have undertaken several research visits in the subsequent years. I visited Hong Kong to work in rotating fluids with Prof Vladimirov. before his appointment at Hull. I often travel to University College, London, to work with Prof. F.T. Smith, and I have had extended stays at the University of Exeter and ,University of Western Australia, Perth, on both occasions to work with Prof. Andrew Bassom.
Research Interests My research interest lies in the general area of fluid mechanics. Although this covers a very wide range of research activity, my main expertise lies in high Reynolds number viscous flows.

My initial investigations focused on the phenomena of boundary layer separation, both for steady-state and unsteady flows. I have also been interested in the stability of shear layers and boundary-layer flows, with particular emphasis on Tollmien-Schlichting, Gortler, and Kelvin-Helmholtz waves. This also led to an interest in sound generation.

I am also interested in Stefan-like problems involving heat and mass transfer, such the impact of freezing/boiling water droplets on aerofoils. This emanates from my PhD thesis (under Eric Watson) an investigation into the melting of ice-shapes.
